Bitstruct restrictive casting

[cbuttner]

bitstruct Foo : int {
  bool a;
}

bitstruct Bar : int {
  bool a;
  bool b;
}

fn void bitstruct_cast() {
  Bar bar;
  Foo foo = (Foo)(int)bar;
  //        ^^^^^^^^^^^^^
  // Error: You cannot cast 'Bar' to 'Foo'

  // This is fine:
  int bar_int = (int)bar;
  Foo foo = (Foo)bar_int;
}

Is this intentional or a bug?

[cbuttner]

Actually I forgot bitcast could also be applied here. But this is still a little confusing.

That looks like a bug.

Does this work now?

[cbuttner]

Looks good now, thanks.
